Inline Current Monitor for Automotive Fuse Circuits

This tester measures DC current on mini and standard blade fuse circuits up to 20A and 48V. It plugs inline with the original fuse so the circuit stays live while you read the draw. The 0.01A resolution lets you spot parasitic drains that a basic multimeter might miss. Designed for DIYers and technicians troubleshooting overnight battery loss.

Backlit LCD Readout and Integrated LED Work Light

The display shows live current with polarity indication so you can confirm power-side versus load-side orientation at a glance. A built-in LED illuminates dark fuse boxes under the dash, in the engine bay or in the boot. Power comes from an internal battery so no external supply or cable disconnection is required during testing.

Replaces Guesswork and Disconnected Multimeter

Instead of pulling fuses one by one or breaking the circuit for a clamp meter, you keep the fuse in place and read the value instantly. The jump is worth it when you need to compare tiny draws across multiple circuits without losing memory settings or waiting for modules to sleep. Not suited for AC circuits, high-voltage systems or currents above the rated limit.

Questions about this item

How do I install this probe tester in a mini or standard blade fuse slot?

Remove the original fuse, insert it into the tester, then plug the tester into the empty fuse slot to read current on the LCD.

What maintenance will this inline current monitor need later?

Replace the internal battery when the backlit LCD dims or readings become unstable.

What limit appears first during sustained use on a 48 V circuit?

The 20 A maximum current rating will be reached before the 48 V voltage limit.
